For everybody fighting with occasional clipping (or perfectionists wanting to test everything) you should try the attached sample, udial.

Testing:

play the sample in your favourite player (decoded or not, having disabled all DSPs and EQs that can interfere)

if the output sounds weird at any time you should:

lower the output vol. in your soundcard config (should be the speaker icon in your system tray).

For some soundcards 48kHz is better (audigy 2 etc.).

lower the vol. till the sample doesn't sound weird at any time.

The output will sound really weird if your settings clip.Your output can occasional clip without you knowing/hearing it. But for us perfectionists this will theoretically give a better quality output.

ATTENTION: Play this sample at a low volume anytime, even if you hear nothing special! It can be very harmful to equipment and/or your ears.It's strongly recommended to use some very cheap (PC) speakers if you want to test this,otherwise you might really ruin your tweeters (it has happened several times already).
